HEATING-STOVE.

Specification of Letters Patent.

Patented Aug. 17, 1920.

Application filed August 28, 1917. Serial No. 188,639.

To all whom it may concern.-

Be it known that 1, Dnwrr'r G. ()ONKLiN, a citizen of the United States, residing at Mount Arlington, in the county of Morris and State of New Jersey, have invented certain new and useful Improvements in Heating-Stoves, of which the following is a specification.

This invention relates to an improvement inheating stoves and more particularly to a stove of this character adapted to use and burn hydro-carbon liquid, or other liquid or gaseous fuel.

An object of my invention is to provide a stove which is so constructed that it is light and compact but at the same time is so designed that the full heat efficiency for the fuel consumed is obtained and this heat is disseminated at and distributed, within the room or other place being heated, near the floor, to thus give more even heat to the an.

A further object resides in providing a heater which is so constructed that smoke, gases or other vitiatin and deleterious fluids thrown off in the initial combustion of the fuel are caught and resubjected to the action of heat, at the same time being combined with new fresh air and thus breaking up the composition thereof andeliminating the injurious effects.

With the above and other objects in view, which will be in part described and in part understood from the specification, drawings, and claim, my invention consists in certain novel features of construction and combination ofparts which will be hereinafter more fully .set forth. In the drawings v Figure 1 is a view inside elevation showing a stove constructed after the manner of my invention;

Fig. 2 is a vertical sectional View taken through the structure as shown in Fig. 1;

Fig. 3 is a top plan view;

Fig. 4 is a transverse sectional view taken on the line 4.-4 of Fig. 5 and looking in the direction indicated byithe arrows; and,

Fig. '5 is a fragmentary detail view to better show the location of draft openings 'for the supply of fresh air; I

The fuel reservoir- 1 is here illustrated as being an oil containing tank constructed in the form and much after the manner of the fuel reservoirs as now used in oil stoves, and the burner 2 is shown as being of the tubular wick type. A base frame 3, which is preferably made up of strap iron or strap metal work has projecting fingers 4 mounted in conjunction therewith to fit under a rim 5 on the fuel reservoir 1 and thus mount and support this reservoir to be carried by the base 3. Uprights 6 are secured on and car ried by the base structure 3 and at their upper ends have a ring 7 mounted, this ring in turn supporting a substantially bowlshaped reflector 8 which is provided with an opening through the center for the reception of the burner 2 and. has a sleeve 9 provided to house around the burner. This reflector has a rim 11 formed therearound and the ring 10 is hingedly mounted at 11 on the rim to fit down therein, a spring latch, or other suitable form of fastening, as indicated at 12, being provided to secure the ring in a position in which it closes down within the rim.

It is the intention that a casing shall be carried above'the reflector 8 and the ring 10 is employed as a proper support therefor, but of course it is understood that where the casing is carried on this ring it can be opened by swinging of the ring to ive access to the reflector and the burner. K second ring 13 is provided as a part of the main supporting structure for the casing, and upright mem bers 14 are secured at suitably spaced points in conjunction with the ring 10 and then after being extended to and connected with the ring 13, are bent or drawn in to take substantially a conical form.

A flue 15, which is preferably of sheet metal is formed to take substantially the shape of a long truncated cone, and this flue is extended substantially up through the apex of the conical frame structure as formed by the members 14, so that the larger or flared end thereof is disposed directly over and somewhat above the burner 2 as the same protrudes into the reflector 8 through the sleeve 9 while the constricted end of this flue 15 opens vertically upwardly. An annular member 15' surrounds the lower end of the cone member and the upper ends of the strips 14 are secured to said annular memberasshown. An outstanding and bell shaped flange 16 is provided around the lower end of the flue 15 and thus a deflecting hood is provided while at the same time the cross sectional area of the flue is kept sufficiently restricted that a proper draft therethrough will be accomplished.

The casing frame structure as formed by the rings ll) and 13 and the members 14 has mica panes 14 fitted therein to form an air-tight casing, and thus, as the casing structure is closed down so that the ring 10 fits within the rim of the reflector 8, substantially a direct draft will be provided through perforations of the collar 17 of the burner 2 and up through the open top end of the flue 1.3. At its rim edge the reflector 8 has a plurality of draft openings 22 provided,these draft openings being so located that when the ring 10 is closed down they establish communication from the interior of the casing to the atmosphere.

A heat distributing drum 18 has a perforated side Wall 19, and the bottom side of this drum has an opening 20 provided therethrough which is of larger size than the open upper end of the flue 15, suitable supporting brackets 21 being provided to mount this distributing drum 18 over the open top end of the flue.

In the use of the stove as described, kerosome oil or other suitable fluid fuel will be supplied to the reservoir 1 and then by releasing the latch 12 and swinging back the casing structure upon its hinged mounting at 1-1, the stove can be lighted at the burner it being understood that the flame will rise within the reflector 8. When the casing is again swung down to the position that the ring 10 fits within the rim of the reflector the only communication to the casing is through the perforations of the collar 17 and through the openings 22 in the rim of the reflector, and an outlet is provided through the flue. Due to the fact that with the circular wick burner the tendency is for the heat and products of combustion. to expand outwardly, the main volume of heat, smoke, gases, and the like will rise between the edge of the bell 16 and the sides of the easing into the u'per part of the casing around the flue. owever, due to the increase of temperature at the upper end of the flue and the fact that a part of the products of combustion will rise therethrough a natural draft is created through this flue. The natural draft through the flue willcause atmospheric air to be taken in through the draft openings 22 formed through the rim of the reflector, and consequently this air will flow into and combine with the rarefied air in. the flue to again load this air with oxygen. As the rarefied air has the atmospheric air combined and mixed therewith, it will become heavier and will fall down over the bell 16 to be resubjected to the heat of the flame and tube drawn into and carried through the flhe 15 to be discharged into the drum 18, from which the products of combustion will escape from the perforated side wall 19 or through the opening 20.

From the foregoing it will be seen that I have provided a heatii'ig stove which has the parts thereof so constructed and arranged that kerosene oil or other liquid or gaseous fuel and perhaps even some of the so-called solid or semi-solid fuels can be used and with which stove structure the full efliciency in heat conversion is accomplished while at the same time the heat is disseminated and distributed to accomplish the most efficient heating action and further it will be noted that by the reburning of the smoke and consequent conversion of the same into heat energy not only a greater efficiency is accomplished but a stove structure is provided which is extremely clean and free from the usual objections when placed in use.

\Vhile in the foregoing l have shown and described only one specific form and construction of the stove and have set forth the parts as bein fitted and assembled in one predetermine relation, it will of course be understood that a number of changes and variations might beresorted to such as substitution of other materials or parts for those herein specifically set forth, without departing from the spirit and scope of my invention, in view of which fact I wish to be limited only to such points as may be set forth in the claim.

I claim A heating stove comprising a reservoir and burner, an open work frame structure surrounding the reservoir, :1 horizontal bowl shaped reflector, a depending sleeve formed centrally of the bowl to surround the burner, an annular rim formed upon the periphery of the reflector, a casing comprising spaced rings one of which rest within the rim of the reflector, strips connecting said rings, the upper terminals of the strips being extended beyond the upper ring and bent toward each other, a ring connecting said terminals of the strips transparent panes held between the strips, a substantially conical flue held within the ring, a flange on the lower end of the flue disposed above the burner the lower edge of the flange and the top edge of the rim lying in the same horizontal plane, and a perforateddrum mounted upon the upper end of the fine.

In testimony whereof I aflix my signature in presence of two witnesses.
